New Delhi: A video posted by a UFO hunter channel on YouTube – UFOmania – showing spooky artefacts being unearthed in Mexico has compelled conspiracy theorists to claim that aliens have visited Earth before and are certainly living among us.

According to the video, some of the sculptures and artefacts unearthed contain spaceships and faces of mysterious creatures with wide eyes and abnormally large heads.

Alien buffs believe that the artefacts are approximately 5000-years-old and claim that no creature existed on Earth that had a similar appearance to the newly discovered artefacts.

They believe that aliens might have visited our world at some point in the past and humans might have attempted to create a replica of their features with the help of spooky artefacts.

The description of the video says: Many will know the Klaus Dona Artefacts. There are Tons more where they came from. More and more locals and farmers are showing their private Artefacts. Fortunately, they did not give their Artefacts to the Smithsonian Institute and the like for further Analysis.

Earlier this month, what is believed to be the first sighting of 2018, a vertical UFO was spotted flying over Baja, Mexico.

Now, with this adding fuel to the fire, the conspiracy theorist circuit is buzzing with the belief that that aliens have visited our planet and are continuously monitoring us.

Previously, alien hunters have also spotted numerous artefacts on Mars as well as the moon. From a goblin face and a war base to a statue of Gautam Buddha and a tree stump, hunters have left no stone unturned to turn scientists' attention to the possible existence of aliens and their 'human-like' culture.

The search for alien life has been going on for years and those involved in alien hunting or UFO hunting have many a time, come close enough to provide evidence justifying it.

While many UFO/alien hunters from around the world have sworn that extraterrestrial life exists, NASA has dismissed these claims, leading alien hunters to believe that the space agency is deliberately trying to hide alien existence.
